Agriculture is the main source of terrestrial emissions of N2O, a potent greenhouse gas and the main cause of ozone layer depletion. The reduction of N2O into N2 by microorganisms carrying the nitrous oxide reductase gene (nosZ) is the only biological process known to eliminate this greenhouse gas. Recent studies showed that a previously unknown clade of N2O-reducers was related to the capacity of the soil to act as an N2O sink, opening the way for new strategies to mitigate emissions. Here, we…

Peaks of in situ N2O emissions are influenced by N2O‐producing and reducing microbial communities across arable soils
It is found that the low N2 O emission rates were mainly explained by variation in soil properties, while the high rates were explained byVariation in abundance and diversity of microbial communities, which lay the foundation for a better understanding of the response of N 2 O-reducing bacteria to agricultural practices and how it may ultimately affect N1 O emissions.
NirS-type N2O-producers and nosZ II-type N2O-reducers determine the N2O emission potential in farmland rhizosphere soils
PurposeDenitrification process in agricultural fields is a large source of nitrous oxide (N2O) emitted to the atmosphere. The rhizosphere soils tend to be the hotspots of denitrification in
Ecology of N2O reducing bacteria in arable soils
Overall, the recently identified clade of N2O-reducers was more sensitive to environmental variables than the previously known clade (nosZI), and the community structure of these two groups was explained by common and uncommon soil properties suggesting niche specialization between the two N 2O- reducers.
Beyond denitrification: The role of microbial diversity in controlling nitrous oxide reduction and soil nitrous oxide emissions
Recommendations are provided to accelerate advances in understanding the role of the diversity of N2O reducers in regulating soil N2 omissions and the potential ecological significance of Clade II NosZ.
Imprint of management on microbial communities in arable soil
Arable soils are a major source of the greenhouse gas nitrous oxide (N2O), emissions of which are directly linked to increased use of N fertilizers. Microbial communities that drive N cycle processes
Soil N2O emission potential falls along a denitrification phenotype gradient linked to differences in microbiome, rainfall and carbon availability
A sustained correlation between microbiome and N2O emission potential (N2O/(N 2O+N2)) in the absence of a pH effect is revealed and features may indicate a conserved NO inhibitory mechanism across multiple effectors (rainfall, community composition, carbon availability).
Effects of biochar on nitrification and denitrification-mediated N2O emissions and the associated microbial community in an agricultural soil
The inhibitory effects of biochar on N2O emissions from nitrification might be attributed to the direct immobilization and adsorption of inorganic N by biochar and to its promotion of the genus Rhodococcus of nirK-typeDenitrifiers and the genera Cupriavidus and Pseudomonas of the nosZ-type denitrifier.
Ecological and physiological implications of nitrogen oxide reduction pathways on greenhouse gas emissions in agroecosystems.
It is highlighted how dissimilatory nitrate reduction to ammonium (DNRA), an alternative N-oxide reduction pathway, may be used to reduce N2O production and N losses via denitrification, which add to the net carbon footprint.

The unaccounted yet abundant nitrous oxide-reducing microbial community: a potential nitrous oxide sink
A comprehensive phylogenetic analysis of the nosZ gene coding the N2OR in genomes retrieved from public databases revealed two distinct clades of nosZ, indicating a physiological dichotomy in the diversity of N2O-reducing microorganisms.
Impacts of nitrogen application rates on the activity and diversity of denitrifying bacteria in the Broadbalk Wheat Experiment
It is concluded that bacteria containing nirK are most probably responsible for the increased denitrification potential associated with nitrogen and organic carbon in this soil.
Intergenomic Comparisons Highlight Modularity of the Denitrification Pathway and Underpin the Importance of Community Structure for N2O Emissions
It is observed that co-occurrence patterns of denitrification genes were not randomly distributed across taxa, as specific patterns were found to be more dominant or absent than expected within different taxonomic groups, thus underpinning the importance of community structure for N2O emissions.
Importance of denitrifiers lacking the genes encoding the nitrous oxide reductase for N2O emissions from soil
A proof of principle that the inability of some denitrifiers to synthesize the nitrous oxide reductase can influence the nature of the denitrification end products is provided, indicating that the extent of the reduction of N2O to N2 by the Denitrifying community can have a genetic basis.
Biological sources and sinks of nitrous oxide and strategies to mitigate emissions
The outcomes of an interdisciplinary meeting, ‘Nitrous oxide (N2O) the forgotten greenhouse gas’, held at the Kavli Royal Society International Centre, from 23 to 24 May 2011 are summarized and the conclusions reached regarding the biological sources and sinks are summarized.
Impaired Reduction of N2O to N2 in Acid Soils Is Due to a Posttranscriptional Interference with the Expression of nosZ
It is hypothesized that the reason is that denitrifying organisms in soils are unable to assemble functional N2O reductase (N2OR) at low pH, as shown to be the case for the model strain Paracoccus Denitrificans.
Unexpected nondenitrifier nitrous oxide reductase gene diversity and abundance in soils
It is demonstrated that diverse microbial taxa possess divergent nos clusters with genes that are related yet evolutionarily distinct from the typical nos genes of denitirifers, and that nondenitrifying populations with a broad range of metabolisms and habitats are potentially significant contributors to N2O consumption.
Detecting Nitrous Oxide Reductase (nosZ) Genes in Soil Metagenomes: Method Development and Implications for the Nitrogen Cycle
This study provides a bioinformatics strategy to reliably detect target genes in complex short-read metagenomes and suggests that the analysis of both typical and atypical nosZ sequences is required to understand and predict N2O flux in soils.
